5G user experiences rely on a tightly synchronized 5G fronthaul network, highly accurate time synchronization testing will be key to assuring the promise of 5G. As discussed in our previous blog, 5G user experiences that require ultra-fast speeds or ultra-low latency pose significant performance demands on the 5G radio and fronthaul networks. Fact is, enhanced radio […]
The TDR (Time Domain Reflectometer) has been used in cable networks as an effective tool to find faults for decades. So why consider changing anything? If it isn’t broke don’t fix it, right? As TDR instrument development has been neglected, there is now an opportunity for improvements as can be seen in these points: Any […]
The prescription for precise SSB configuration As 5G moves from the lab into the field, service provider (SP) deployment teams are learning about the nuances of different 5G NR implementations. Unsurprisingly, all 5G NR implementations are not the same, but getting a solid dose of understanding on beamforming and the impact of profile configuration is […]
The importance of Gartner Magic Quadrant research to assess vendors and their technologies is well known. The Critical Capabilities is a sister document, published in conjunction with the MQ. In the MQ, Gartner synthesizes numerous inputs into two broad groups; “Ability to Execute” and “Completeness of Vision”, and then plotting them on a graph, Gartner […]
Why Signal Leakage, Why Now? Ingress has been the single largest thorn in the side of cable operators since the advent of CATV plants, only to be aggravated by the introduction of two-way services. Despite decades of innovation, the silver bullet solution to fully address this problem remains elusive. Why Ingress Is Such a Challenge: […]
When last we gathered around the soft glow of the monitor, we shared the oft-told tale of troubleshooting random user complaints and the importance of scoring and storing instead of ignoring. This time, let’s turn the pages of a related story – a fish story so to speak… In the rivers of data that flow […]
Day in, day out. You make a difference—connecting families, accelerating commerce, dispatching help—you diligently maintain and improve the networks and services that improve lives. Do you remember how you got here? The journey? All the hard work? We do… (sneak peek, if you can’t wait to the end of this post). Scrappy Underdog Think back, […]
Software-defined WAN is not just a service, but a new way of doing business. What’s old is new again ☺. Software-defined anything has a tendency to bring technology cycles back to life… remember SDN? Software-defined WAN is not just a service, but a new way of doing business. SD-WAN transformation is required – for service […]
It’s the tale as old as timestamps: A random user complains of a random performance problem When someone is available to assist the user, the problem is no longer occurring The available data doesn’t provide any real clues Wait a while. Repeat. Why is this story still being told? With all the advancements that have […]
Advancements in LiDAR (Light Detection and Ranging) system technologies are rapidly paving the road for intuitive self-driving systems. The push for automotive innovation does not come without addressing a unique set of challenges with functionality and safety at the forefront. As a leading manufacturer of high-performance optical filter technology for LiDAR systems, VIAVI Solutions has […]
